Definición de cavalry en inglés:

sustantivo (plural cavalries)

His army's main power was based on his cavalry - horse borne soldiers.

William's plan was to use the archers first to send their arrows into the English ranks, followed by the infantry in hand-to-hand combat and to finally advance with the cavalry who had the height and power of being on horseback.

In previous wars, horsed cavalry had performed such a role, but cavalry were generally of little use in the trenches of the Western Front.
